BACKGROUND Glucokinase (GK) is a metabolic enzyme encoded by the GCK gene and expressed in glucose-sensitive tissues, principally pancreatic islets cell and hepatocytes. The GK protein acts in pancreatic islets as a "glucose sensor" that couples fluctuations in the blood glucose concentration to changes in cellular function and insulin secretion. GCK and GK have proposed importance in the devel...

During December 2016-February 2017, influenza A viruses of the H7N2 subtype infected ≈500 cats in animal shelters in New York, NY, USA, indicating virus transmission among cats. A veterinarian who treated the animals also became infected with feline influenza A(H7N2) virus and experienced respiratory symptoms. To understand the pathogenicity and transmissibility of these feline H7N2 viruses in ...

We describe the metagenomics-derived feline enteric virome in the faeces of 25 cats from a single shelter in California. More than 90 % of the recognizable viral reads were related to mammalian viruses and the rest to bacterial viruses. Eight viral families were detected: Astroviridae, Coronaviridae, Parvoviridae, Circoviridae, Herpesviridae, Anelloviridae, Caliciviridae and Picobirnaviridae. S...

A 1-year-old female domestic cat showing progressive locomotor and neurological problems for 4 weeks was euthanized and examined. On autopsy, the brain was macroscopically normal. Test results for rabies, feline spongiform encephalopathy, feline infectious peritonitis, feline immunodeficiency virus, feline leukemia virus, and feline herpes virus (type I) were negative. Histologic examination of...

The distribution of the nonstructural protein 1 (NSP1) alleles from human strain AU-1 and canine strain K9 among rotaviruses of human, feline, canine, bovine, and simian origin was studied by a dot blot hybridization assay. Human and feline strains belonging to the AU-1 genogroup had the same NSP1 allele, while canine and feline strains belonging to the canine-feline genogroup shared another NS...

background and objectives: feline herpesvirus-1, feline calicivirus and chlamydophila felis are the main causes of feline upper respiratory tract disease. this study was conducted to identify of fehv-1, fcv and c. felis infections in domestic cat population and also to estimate the prevalence of each specific infection in iran. materials and methods: the ocular conjunctiva and oropharyngeal spe...

The discovery of human retroviruses in the early 1980s revealed the existence of viral-encoded non-structural genes that were not evident in previously described animal retroviruses. Based on the absence or presence of these additional genes retroviruses were classified as 'simple' and 'complex', respectively. Expression of most of these extra genes is achieved through the generation of alterna...

Mammalian genomes harbor a large number of retroviral elements acquired as germ line insertions during evolution. Although many of the endogenous retroviruses are defective, several contain one or more intact viral genes that are expressed under certain physiological or pathological conditions. This is true of the endogenous polytropic retroviruses that generate recombinant polytropic murine le...
